(We all know that Ethernet devices, such as network cards, have their own globally/unique MAC addresses. They use MAC addresses to transmit Ethernet packets, but they cannot identify the IP addresses in our IP packets. When carrying out IP communication in the Internet, a protocol is needed to establish the correspondence between the IP address and the MAC address, so that the IP data packet can be sent to a determined place. This is ARP (AddressResolutionProtocol, Address Resolution Protocol).
